john: california, nevada, florida, and now michigan have legalized self driving cars, department of think it was, national department -- department of transportation, national department said you cannot really legalize it only limited t*eufts and no sales. >> and other bigger questions, i am sure other lobbyists some automakers may be cautious with driver less cars for example google is using lexus cars and other auto companys to outfit their system on top of car. >> in the event of an accident who is liable? the other legal questions still. >> and my computer crashes sometimes. >> so does mine. john: google has driven this car cross country many times only time there were accidents when a human was behind the wheel, they never had an accident. >> when you think about car accidents in u.s., and fatalities, that are because of human error, that is really the future that google is trying to push forward, idea that with more driverless cars you will have perhaps less fatalities. john: i would say, we have a hundred deaths per day in cars driven by humans and human error is main reasons. comp
